Abstract

The utility model relates to a pair of trachea inserting tube forceps, which belongs to a medical device, particularly a special device which is used for inserting an air guide tube in a trachea. The forceps is provided with a conventional handle with a finger ring. The utility model is characterized in that the lengths of two holding arms of the forceps are unequal; the end of the long holding arm and the position which is about 3 centimeters to 7 centimeters far from the long holding arm are both provided with a holding piece with a slot; the end of the short holding arm is provided with a supporting arm which is incurved and is not arranged on the same plane with a holding rod; the end of the supporting arm is provided with a holding piece with a slot; the distance from the holding piece of the short arm to a shaft is about half of the sum of the distances from the two holding pieces of the long arm to the shaft. The utility model can stably hold the tube and can freely bend the air guide tube, and the trachea can be conveniently inserted.

Description

The tracheal intubation pincers

This utility model relates to medical apparatus and instruments, relates in particular to the special equipment that airway is inserted trachea.

As everyone knows, when implementing bigger operation on oral cavity, when perhaps the patient that respiratory tract is stopped up rescues, often need airway is inserted patient's trachea, to guarantee eupnea.At present, the most frequently used apparatus was a Magill formula intubating forceps when airway was inserted trachea, and this intubating forceps structure as shown in Figure 1.Because two clamping limbs of these pincers all are linear, and the front end of its two isometric clamping limbs is into two mirror symmetry annuluss, so these pincers have only stable holding function, and can not be with the airway bending.But, when no matter inserting catheter tube, must just can carry out trachea through one 90-120 ° bent angle to the glottis place from the oral cavity or from the nostril.So the Magill intubating forceps can only be delivered to glottis to airway, further airway is inserted trachea, can only push away, revolve airway, the tracheal wall that makes airway head on the glottis place produces crooked, and enters trachea along wall.This method can be brought unbearably misery to patient undoubtedly, has also damaged the tracheal wall mucous membrane tissue.

For overcoming the shortcoming of Magill intubating forceps, doctor Aillon has designed and has led device (referring to Fig. 2) in the Aillon trachea.This device is made of semi-circular elasticity handgrip and two not isometric arms that are contained in the handgrip opening; Two arm front ends all curve inwardly, and two arms are connecting to the mode of sliding along brachium, lead device in the Aillon trachea, rely on two arm end bending sections along long to relative distance shortening clamping airway or force the airway end bent, make airway more easily insert trachea, it has improved the intubate effect to a certain extent.But, also should see: the bending section of this device arm, in case determine, then the airway caliber of its energy clamping and the scope of airway bendable angle have also just been determined; In addition, thisly makes the airway bending to the mode that changes arm end two clamping member distances, very easily cause damage being attached to air bag on the airway, that blood stains flow into trachea when preventing to perform the operation along long; So this airway device is still unreasonable in design.

Purpose of the present utility model is: the structure of improving Magll formula tracheal intubation pincers, make it the airway of clamping all size, and can airway is crooked arbitrarily in 180-90 ° scope, smoothly airway is inserted trachea, and do not damage the air bag of setting up on the airway.

This utility model for achieving the above object, the technical measures of taking are as follows:

This tracheal intubation pincers (referring to Fig. 3) also are to be coupling with axle by two pincers of the clamping limb sheet that is provided with the handgrip 2 that refers to circle 1 and is provided with bare terminal end that fuses to form.Its characteristics are: described two clamping limbs 3 that link to each other with handgrip respectively and 4 are not isometric; Wherein, in the end of long clamping limb 3 with apart from end 25-70 millimeter place, respectively be arranged with a holding piece 5,5, this two holding piece is roughly perpendicular with plane, two clamping limb places, two holding pieces 5, side has the arcuate groove that parallels with clamping lever 3 within 5, described short clamping limb 4, its end is provided with a support arm 6 that curves inwardly roughly with the rectangular long 5-25 millimeter of short jig arm bar, support arm 6 rotates the face that constitutes with long clamping limb around axle O and becomes space parallel, and keep the 0.2-5 mm distance, support arm 6 ends be provided with long clamping limb on two holding pieces point to identical holding piece 7, holding piece 7 inboards have and lack the arcuate groove that clamping limb parallels.Described short holding piece approximates on the long clamping limb two holding pieces to axle O half apart from sum to axle O distance.

Description of drawings:

Fig. 1 Magill formula tracheal forceps.

Lead device in Fig. 2 Aillon trachea.

This tracheal intubation of Fig. 3, wherein:

1-refers to circle, the 2-handgrip, and the long clamping limb of 3-, 4-are lacked clamping limb, and 5, the 5-holding piece, 6-support arm, 7-holding piece, 0-axle.

Embodiment and effect:

The Magill formula intubating forceps that this human is old is changed a social system by above-mentioned design, and through on probation, these pincers are the airway of clamping all size stably really, and can be in 180-90 ° of scope any crooked airway; To same airway clamping repeatedly of setting up air bag, crooked hundreds of times, air bag is still intact.After sterilization, be directly used in clinically, it can crooked well airway, and airway is aimed at the patient's trachea axis, successfully airway is inserted patient's trachea, and is quick and convenient, exempt to make patient suffer needn't misery and mucosa injury.The above results shows that this utility model has reached intended purposes fully.

Claims

1, a kind of tracheal intubation pincers, form with the axle connection by two pincers sheets that are provided with handgrip, clamping limb, it is characterized in that: the clamping limb of described two pincers sheets is not isometric, the end of long clamping limb and apart from 25-70 millimeter place, end, respectively be arranged with a holding piece, this two holding piece and plane, two clamping limb places approximate vertical, all there is the arcuate groove parallel with long clamping limb two holding piece inboards; Short clamping limb, the end is provided with a support arm that curves inwardly rectangular approximately long 5-25 millimeter, support arm and the long clamping limb face that constitutes that sways becomes space parallel, and maintenance 0.2-5 millimeter distance, arm end be provided with point to long clamping limb on the identical holding piece of holding piece sensing, have on the holding piece and lack the parallel arcuate groove of clamping limb.

2, tracheal intubation according to claim 1 pincers is characterized in that: the holding piece on the described short clamping limb to the distance of axle approximate on the long clamping limb two holding pieces to axle apart from half of sum.
